Details
__construct(FormRendererEngineInterface $engine, CsrfTokenManagerInterface $csrfTokenManager = null)
Constructor.
FormRendererEngineInterface getEngine()
Returns the engine used by this renderer.
setTheme(FormView $view, mixed $themes)
Sets the theme(s) to be used for rendering a view and its children.
string renderCsrfToken(string $tokenId)
Renders a CSRF token.
Use this helper for CSRF protection without the overhead of creating a form.
Check the token in your action using the same token ID.
$csrfProvider = $this->get('security.csrf.tokengenerator');
if (!$csrfProvider->isCsrfTokenValid('rmuser_'.$user->getId(), $token)) {
throw new \RuntimeException('CSRF attack detected.');
}
string renderBlock(FormView $view, string $blockName, array $variables = array())
Renders a named block of the form theme.
string searchAndRenderBlock(FormView $view, string $blockNameSuffix, array $variables = array())
Searches and renders a block for a given name suffix.
The block is searched by combining the block names stored in the form view with the given suffix. If a block name is found, that block is rendered.
If this method is called recursively, the block search is continued where a block was found before.
string humanize(string $text)
Makes a technical name human readable.
Sequences of underscores are replaced by single spaces. The first letter of the resulting string is capitalized, while all other letters are turned to lowercase.
